Cyst (Definition) 1  A cyst is a structure or mass that consists of a cellular lined sac. 2  Ovarian torsion is a condition in which a woman's ovary twists upon its arterial supply, thus depriving it of oxygenated blood. 3  When a hollow structure like an blood vessel, a cyst, bladder, bowel, etc bursts we call that a rupture.
A complex ovarian cyst is simply a cyst that contains both fluid and solid material. Also known as a complex cyst on ovary or complicated ovarian cyst, it often develops when the process of ovulation ends abnormally. If not treated, a complex ovariian cyst can cause serious medical problems.
